4.5.1 MSP430 Trigger Control

  1. Enter Additional Hardware Modes.
  2. Select Mode 0 (00000’b) using the increment mode button (+).
    • B1 – Select the on-board ERM
    • B2 – Select the on-board LRA
    • B3 – Trigger Select (1 = Internal Trigger, 2 = Ext. Edge, 3 = Ext. Level)
    • B4 – Trigger the waveform sequence using the MSP430.
  3. Fill the waveform sequencer with waveforms using the external I2C port.
  4. Choose either the on-board ERM or LRA using buttons B1 or B2.
  5. Select either External Edge (2) or External Level (3) trigger using the B3 button. The trigger type appears in binary on the mode LEDs.
  6. Apply the trigger signal to the IN/TRIG pin by pressing the B4 button.
